ROD AND 0F MAKING To all whom it may concern Be it known that I,rinnnenn J. Gau'rfarnn, a citizen oft-he United States, and resident ofDetroit, Wayne County, State oile lichigan have invented. certain newand useful improvements in Rods and Methods of Making Same, of which thefollowing is a specification.

This invention relates to rods and more particularly to yoke ended rodsand to methods of makingsuoh rods.

In many machines, such for instance, as motor vehicles, it is necessaryor desirable to provide for lost motion in the connections between twooperative elements of the machine. For' this purpose itis common to useconnecting links or rods having slotte'd or bifurcated end portions oryokes.

r This invention has for one of its salient objects, to provide a rod ofthis character that willbe rigid and strong in construction and that maybe inexpensively manufactured.

Another object is to provide a method of making rods of this characterby means of which they may be manufactured cheaply and efficiently.

Other objects will appear from the following description taken inconnection with the drawings which form a part of this specification andin which:

Fig. 1 is a view in elevation showing the body portion of the rod, thisshowing being broken away;

Fig. 2 is a view similar to Fig. 1, but showing the body portion afterone end has been swaged;

Fig. 3 is an edge view of the'fiat bar stock from which the yoke or slotportion of the rod is made;

Fig. 3 is a transverse sectional view of the bar shown in Fig. 3;

Fig. 4 is a view similar to Fig. 3 but showing the slot portion or yokeof the rod after the flat bar has been bent upon itself and the freeends have been swaged;

Fig. 5 is an end view of the construction shown in Fig. 4;

Fig. 6 illustrates another form of end portion open at one end andwhich-is formed from a pair of flat bars instead of from a single bar,this view corresponding to Fig. 4;

Fig. 7 shows the yoke illustrated in Fig. 4:

butt welded to the body portion shown in Fig. 2; and

Specification of Letters Patent.

Application filed March 20,

Patented Filiay i 1929. Serial No. 367,480.

Fig. 8 is an edge view taken at right angles to Fig. 7 showing the yokeended rod after the joint has been machined to remove the excess metal.

Referring to the drawings, the body portion 20 ot'the yoke ended rod ispreferably formed of tubularmaterial for strength, and in this case thefirst step in the method of making the rod consists of swaging one endof the tubular'rod shown at 21, the tubular rod being closed at thisswaged end to form a solid rod. 7 Y

The yoke or slot portion illustrated in Figs. 3 to 5 inclusive is shownas formed from flat bar stock shown at 22, this bar being bent uponitself as shown in Fig. 4:, the side portions 23 of the slot beingspaced apart The free ends of the bar are then swaged as shown at 24: toa position in which they are juxtaposed with respect to each other,thereby closing the slot. The two juxtaposed ends 24 of the yoke arethen simultaneously butt welded as shown at 25 to the end 21 of the bodyportion 20 of the rod and this joint is then finished by machining or inany other suitable manner to remove the excess metal.

In the form of the invention illustrated in Fig. 6, the slot portion ofthe rod is formed 7 of two separate pieces of material or bars, 26, eachof these pieces having one end olfset and swaged as shown at 27 the ends27 being positioned in a manner similar to the ends 24 of the bar 22.The ends 27 of the bars 26 are then butt welded to the end of the bodyportion in the same manner as the ends 24.

From the above description it will be seen that I have provided a simpleand inexpensive method of manufacturing yoke ended rods and that therods so manufactured will be rigid and strong in construction.

While I have, in the above specification, described certain specificembodiments of my invention, it will be understood that the invention isnot limited to the exact method or details of construction specificallyillustrated and described, but that changes may be made withoutdeparting from the spirit or scope of the invention as expressed in thefollowing claims.

Having thus described my invention, what I claim and desire to secure byLetters Patent is:

1. A rod formed of tubular material havtion being solid.

A rod formed of tubular material having integrally united therewith, atone end,

, a slot portion, the portion of the rod adja cent to the slot portionbeing solid.

3. A rod having a body portion formed of tubular'material. and'having aslot portion at one end formed of flat bar material, said body portionand said end portion being integrally joined.

a. A method of forming a rod which consists of swaging one end of atubular body portion, forming a slot member having free ends swaged intojuxtaposition with respect to each other, and Welding the juxtaposed.ends of the slot member to the swaged end of the tubular member.

5. A method of forming a rod which consists of compressing one end of atubular body portion in a manner to close said end, bending a-bar uponitself to form a slot, positioning the ends of the bar intojuxtaposition to close the slot at said end, and welding the closed endportion of the rod to the juxtaposed ends of the bar.

6. Amethod of forming a rod which consists of swaging one end portion ofa tubular rod and butt Welding two juxtaposed ends of a slot member tothe swaged end. portion of said rod.

the free ends of said slot portion to one end of: the, body portion.

9. A method of forming a rod having a body portion and a slot portionwhich consists of swaging one end of the tubular body portion, bending abar upon itself to a form in which the longitudinal portions of the barare spaced apart and the free ends are ofiset to close this slot, and-welding the swaged end of the tubular body portion to the free ends ofthe slot portion.

10. A method of forminga rodhaving a body portion and a slot portionwhich consists of swaging one end of a tubular body portion, bending abar upon itself to aform in which the longitudinal portions of the barare spaced apart, swaging' the-free ends of the bar to close the slot,and butt welding the swaged ends of the slot portion to the swaged endof the body portion.

In .testimony'whereof I aflix my signature.
